But at the end of a long day of work or taking care of the family, schlepping around a Winnie the Pooh bag and suppressing every profanity-laced thought, when parents find their little angels still bouncing with energy, most of them are thinking one thing: “Go the F*** to Sleep.”

Well, author Adam Mansbach finally said it out loud in his new book aptly titled, “Go the F*** to Sleep.”As if a bubble of relief popped on PayPal, the book shot to No. 1 on Amazon — before it was even released.

You could practically hear the collective, “Yeeeeeeeees!” from parents across the country, followed by, “Click — Buy It Now!”

The book won’t be released until next week, but its No. 1 status has been attributed to the fact that a PDF of the book in its entirety was leaked on the Internet, delivering a simultaneous win for paid and free content on the Internet. Hello, winning!

Here’s an excerpt:

“The cats nestle close to their kittens.The lambs have laid down with the sheep. You're cozy and warm in your bed, my dear Please go the f@#k to sleep.”
